Answer:
symmetrical in many ways across a central axis" and "presence of a head".
Explanation:
Bilateral symmetry is a characteristic that many organisms has at which if we divide the body using an imaginary line, we will see two mirror images. Two characteristics that an organism with bilateral symmetry possess are symmetrical in many ways across a central axis (known as well as the sagittal plane), and presence of a head that is at the middle of the central axis. The great majority of organisms posses bilateral symmetry, including the humans.
Answer:
The electron transport chain uses the transfer of ELECTRONS between protein complexes to set up a proton gradient
The function of the proton gradient in mitochodrion it's to provide potential energy that can power ATP synthesis
The answer is B.
Explanation:
Electron transport chains transfer electrons from an electron donor to an electron acceptor. The transfer of electrons aids translocation of protons across a membrane to form proton gradient that produce useful work.
The proton gradient can generate a chemiosmotic potential/proton motive force which supplies potential energy for ATP synthesis through oxidative phosphorylation.
Answer:
In biology, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. ... An active sitecan catalyse a reaction repeatedly as residues are not altered at the end of the reaction (they may change during the reaction, but are regenerated by the end).
